What Exactly Is the Rule of 72?
The Rule of 72 is a way to guess how long it takes for an investment to double. You just divide 72 by the interest rate it earns.
The Mathematical Magic Behind the Rule
The Rule of 72 is simple yet powerful. It uses compound interest. Compound interest is when you earn interest on both the original amount and any interest it earns over time. The formula is: Years to double = 72 / Interest Rate.
For example, with an 8% annual return, your investment will double in about 9 years (72 / 8 = 9).

Here are some real-life examples of the Rule of 72:
| Interest Rate (%) | Years to Double |
|---|---|
| 4 | 18 |
| 6 | 12 |
| 8 | 9 |
This table shows how different interest rates change the time it takes for an investment to double. Knowing this can help you make better financial decisions.
